Storage and Manufacturing
7.1. Storage
M85 module is distributed in a vacuum-sealed bag. The restriction for storage is shown as below.
Shelf life in the vacuum-sealed bag: 12 months at environments of <40
℃
temperature and < 90%RH.
After the vacuum-sealed bag is opened, devices that need to be mounted directly must be:
Mounted within 72 hours at the factory environment of ≤ 30
℃
temperature and < 60% RH.
Stored at <10% RH.
Devices require baking before mounting, if any circumstance below occurs.
When the ambient temperature is 23
℃
±5
℃
, humidity indication card shows the humidity is >10%
before opening the vacuum-sealed bag.
If ambient temperature is < 30
℃
and the humidity is < 60%, the devices have not been mounted
during 72hours.
Stored at >10% RH.
If baking is required, devices should be baked for 48 hours at 125
℃
±5
℃
.
As plastic container cannot be subjected to high temperature, devices must be removed prior to high
temperature (125
℃
) bake. If shorter bake times are desired, refer to the IPC/JEDECJ-STD-033 for bake
procedure.
